钻孔无线电波透视法是地球物理勘探的一种方法,此法用在岩溶地区是基于高频电磁波在灰岩介质中传播途径上迂有炭酸岩类溶洞(空的、充填土砂、充水或堆积物)有着明显的反射、折射、绕射、吸收等变化,借此固定洞穴的范围,不仅可以推断其空间位置、规模,而且可以确定充填性质。实验表明此方法比常用的一些地球物理勘探方法有着较多的优点。我们用重庆煤炭研究所研制的JJT-1型全晶体管化钻孔无线电波透视仪在遵义灌区天门河水库二坝址进行试点。该仪器发射
Drilling Radio-wave-radioscopy is a geophysical prospecting method used in karst areas based on the propagation of high-frequency electromagnetic waves in limestone media with chalcopyrite karst caves (empty, filled with sand, water-filled or Sediment) has obvious reflection, refraction, diffraction, absorption and other changes, thereby fixing the scope of the cave, not only can infer its spatial location, size, and can determine the filling properties. Experiments show that this method has more advantages than some common geophysical prospecting methods. We use the JJT-1 all-transistorized drilling radio-wave radiometer developed by Chongqing Coal Research Institute to carry out pilot projects in the dam site of Tianmen River Reservoir in Zunyi Irrigation District. The instrument is launched
